Has anyone struggled or had issues with fingerprint sensor on s24 ultra. I keep on having issues, says unable to read. Put on sensor again and keeps on locking me out.

I honestly cannot understand why manufacturers persist with this flawed technology. Having just moved over from Apple, I'm starting to regret it. In this day and age, we shouldn't have to choose between protecting our phones or having workable tech. I'm seriously considering sending my S24U back and getting another 15 Pro Max.

For me only it happened if my finger is too dry. Even adding the fingerprint in biometrics also fail. Then i saw someone said in some forum said when after using hand sanitizer, his phone unable to detect his fingerprint. I think the regular tempered glass without glue will have this issue.

I bought the expensive Spigen fingerprint compatable screen protector and the fingerprint scanner doesn't work. Janky as hell.

If you haven't already delete your existing fingerprints and reset them back up and double check the extra sensatativity is turned on @Spidey1980 


Daily Driver > Samsung Galaxy s²⁵ Ultra 512Gb ~ Titanium Black.

The advice I offer is my own and does not represent Samsung’s position.

Mine has completely lost it. I kept noticing my phone unlocking when I'm just holding it or it slides over something in my bag, it's been a nightmare tbh. But I finally worked out the issue, it is accepting any of my fingers as a fingerprint to unlock the phone despite only my right thumb being registered. Then I asked my partner and my friend to try and yes, it accepted their fingerprints and unlocked, not only my phone unlock but all apps that have biometric login set such as my banking apps etc. This is a really scary issue and I've had to turn off biometric all together and just use code. It was even registering items and materials rubbing against the screen as a fingerprint and unlocking at times. Major security issue. I've only had this phone for 2 months, this started about a week ago, I think it was after a certain software update.

I had basically deleted them all and removed the screen protector, then restarted my phone and re added my finger print and it was sorted. I think it was the screen protector brand I used. Will be getting it off Samsung site next time not any old brand

SAMSUNG please note: Your s24U Finger print scanner is not as good as other models. My old s21U had a great relaibel scanner, with any old screen protector. This s24U seems to have an over sensitivity for the finger print scanner. Despite rescanning time after time and maxing out on number of scans - ( I think 4?) It still is a pain. This is so inconvenient that I may send it back for a refund

Same here, I hope this is fixable with a software update... I will not use the phone without a screen protector, of that I'm sure...

I'm coming from the S24 plus and it has no issue, my ultra is becoming very annoying to use due to this problem.

It's the only problem so far, but, unacceptable Samsung... come on, it's your flagship and a very expensive device, fix it ASAP.
